Hello everybody,
Has anyone paired a new module-A with and old module-B (or, vice-versa)?
We have a production 28 / 2001 model Rotax 912 ULS. Recently, we've replaced the sprag clutch. Afraid to brake it again, we also got a new Soft Start type module-A. The idea was to start w/SSM (module-A), then switch to BOTH.
There are 2 separate Kill Switches for L & R (and a rotary Master Switch). "R" commands the module-A.
Unfortunately, there is no info available. We've made the connections (and some corrections) as shown in the attached PNG (changed LEFT (A) 6+4+1 style socket connectors to 6+6 style).
However now, when only "R" is ON, all 8 plugs spark. When only "L" is ON, no spark at all. Also, this way, I'm afraid ATDC (SSM) and BTDC timings of R and L (or, T & B, or, A & B) are mixed.
I am suspecting the connections to the twin black coils (marked as 16) at the bottom of the diagram. From left black coil, the wire goes through the left connector, crosses the lower wire group and goes into the upper group on module-A. Whereas, the old one used to go in the lower group instead.
Any ideas?
New Module-A # 965444 16.1155 (6+6 type connectors)
Old Module-A # 966721 01.1195 (6+4+1 type connectors)
Kind Regards,
Al
